Write a function getScores(...) that is given a string, an int type array to fill and the max number of elements in the array as parameters and returns an integer result. The function will find each substring of the given string separated by space characters and place it in the array. The function returns the number of integers extracted. For example: int values[3]; getScores("123 456 789", values, 3 ); would return the count of 3 and fill the array with...

Write a ML language function stripmin of type
int list -> int list that will return a list from which every
instance of the lowest value has been removed.
Hints:
• Only stripmin itself should be visible at the top level;
•You should have two recursive helper functions tucked away
inside a let … in … end; structure
• Also include a val to avoid having to pass a value that never
changes to one of these functions.

Write a function, int flip(string a[], int n); It reverses the order of the elements of the array and returns n. The variable n will be greater than or equal to zero.

a) You must write a recursive function that takes something of the form: ([(Int, Int, Int), Int, Int) as an argument and returns something of the form: LE(Int, Int, Int)]] which should be interpreted as a list of lists of 3-tuples of RGB values. You may use helper functions if you wish, but your solution must be recursive. You must document the name of your function at the beginning of your code using a comment like -- foo :: ([(Int,...
